My Question or Issue

So I have gone over to Amazon Music HD, primarily because my family can listen to multiple streams with a family plan. If my son has an echo in his room, or I have one in the kitchen, or master bathroom, I can ask to play some music and it won't stop playing on another device. 

I know in the past you can log into a Spotify account per device, but that challenge makes multi room audio impossible. I would like to come back to Spotify, but if I can't have multiple streams playing from a single account (under the family plan!), then I will stay with Amazon Music. Appreciate if anybody has any answers on this one. It's a big feature for me.
